Google's JavaScript Benchmarks

Google Chrome JavaScript execution is currently the fastest. Below is the link to the benchmark suite where you can test your browser. I currently get 1578 with Chrome 2.0.172.31 and only 130 with Firefox 3.0.11. Firefox 3.5 RC2 scores 212. Detailed comparison below:

Edit: Fortunately, this week there was an announcement (what a coincidence) that Mozilla will introduce new JavaScript Just-in-Time compiler with codename TraceMonkey, to replace their current SpiderMonkey engine, that should increase JavaScript performance in Firefox 3.1 anywhere from 2 to 37 times over the previous version of the browser (3.0). Average performance improvement is calculated to be 4.6 which is on par with, if not faster than, current Google Chrome.

I have installed Firefox 3.5 RC2 and the subjective feeling of speed is greatly enhanced compared to Firefox 3.0. To turn the TraceMonkey on, read this article.
